New and efficient synthesis of 5′-amino-5′-(S)-methyl-2′,5′-dideoxynucleosides
Jung, Pierre M. J.,Beaudegnies, Renaud,De Mesmaeker, Alain,Wendeborn, Sebastian
, p. 293 - 297 (2003)
A short, efficient synthesis of 5′-amino-5′-(S)-methyl-2′,5′-dideoxynucleosides 1 has been developed through the diastereoselective addition of methylmagnesium bromide or methyllithium to an intermediate tert-butylsulfinimide.
